Had a bit of a chilly dive on Wednesday! Strange the Poor Knights never get that cold, so imagine my surprise when I glanced down at my D9 and saw the temp: '
-12'

I have defied the laws of physics and was swimming through a solid!!!
I haven't seen any other reference to this, so is it a new problem?
Yes, I have had the upgrade/retrofit thingy - probably what caused it. Having dived since it seems to be fine for the first dive and then go belly up on the rest.
Ho-hum, back it will go - this will be the 4th time
